Looking to re barrel a Mauser 98?

One thing to keep in mind is that with the latest bullets (such as the Hornady 208 AMAX and Berger 215 Hybrid) and newer powders like RL-17, the humble 30-06 is capable of greater performance than many realize. Go with the AI if it floats your boat, but I don't think it will do much for you in real world terms.

If you are wanting a hunting rifle just have it drilled and tapped for a scope,bend the bolt, have a new barrel put on and get a new stock if you want. Bedding the stock is a good optin but that should be a great 30-06. It might keep sub MOA some of the mausers were built to very close tolerances. That would keep your cost down quite a bit.
